Area codes 202 and 771

Area codes 202 and 771 are telephone area codes in the North American Numbering Plan (NANP) for Washington, D.C.

Area code 202 was one of the original North American area codes established in October 1947 by the American Telephone and Telegraph Company (AT&T). After the State of New Jersey with area code 201, the District of Columbia was the second numbering plan area (NPA). Area code 771 was added to the numbering plan area in April 2021 in creation of an overlay complex to mitigate impending telephone number shortages.
